Calling A Console App From A Form App And Some Little Questions

Taklaci Guvercin

I wonder how can i call a console application from a form application is it possible?

1- Write a recursive function to determine a given two strings are anagram or not.

Example anagram words:

Listen = Silent

Elvis = Lives

Admirer = Married

2- Write a recursive function that deletes all vowel characters from a given string.

Example:
Input: akraba
Output: krb

Hi Taklaci,

For the 2nd part solution

Try this...

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace WindowsFormsApplication5
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {

            string s1;
            string s2;
            s1 = "akraba";
            s2 = System.Text.RegularExpressions.Regex.Replace(s1, "[aeiouAEIOU]", "") ;
            MessageBox.Show(s2);

        }

        }
    }

Thanks

Merry Christmas to you too.

It depends what you mean by 'calling' a console application. You can certainly start one from a windows forms application:

System.Diagnostics.Process.Start("myconsoleapp.exe");

To do those two questions using recursive functions, try the following:

// anagram.cs

using System;

class Program
{
static void Main()
{
string[] strings1 = {"Listen", "Elvis", "Admirer", "Vital"};
string[] strings2 = {"Silent", "Lives", "Married", "Alive"};

for(int i = 0; i < strings1.Length; i++)
{
Console.Write("{0} and {1} ", strings1[i], strings2[i]);
bool result = AreAnagrams(ref strings1[i], ref strings2[i]);
Console.WriteLine(result ? "are anagrams" : "are not anagrams");
}

Console.ReadKey();
}

static bool AreAnagrams(ref string s1, ref string s2)
{
if(s1.Length != s2.Length) return false;

s1 = s1.ToLower();
s2 = s2.ToLower();

char c = s1[0];
int index = s2.IndexOf(c);
if(index > -1)
{
s1 = s1.Remove(0, 1);
s2 = s2.Remove(index, 1);
if(s1 == "") return true;
return AreAnagrams(ref s1, ref s2);
}
else
{
return false;
}
}
}

// removevowels.cs

using System;

class Program
{
static void Main()
{
string s = "akraba";
RemoveVowels(ref s);
Console.WriteLine(s);
Console.ReadKey();
}

static void RemoveVowels(ref string s)
{
int index = -1;

for(int i = 0; i < s.Length; i++)
{
char c = Char.ToLower(s[i]);
if(c == 'a' || c == 'e' || c == 'i' || c == 'o' || c == 'u')
{
s = s.Remove(i, 1);
index = i;
break;
}
}

if (index > - 1) RemoveVowels(ref s);
}
}
